The full story

An LLVM-Z80 contributor reports using Claude, Codex and other coding agents to develop and maintain the compiler fork.

The fork targets Z80 and SM83 processors. The contributor says tool use was mixed across the project and cannot reliably be divided into individual tools’ contributions.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
